I like that system. Same gearbox as used on the JB line. Sure like the system better than the JB though. The JB uses a long universal shaft from the front of the tractor, all the way to the rear to the gearbox. The deck pto shaft on the JB has to be removed in order to slip on the rear pto's shaft. Both the JB & the HD uses the same hydro & diff, so I can't understand why the JB uses the harder to use setup. Man, getting late. I better hit the hay!
